The editors of the Edison Papers produced descriptions for each of the folders listed below. These folders can be found in the Thomas A. Edison Papers Digital Edition. They generally include the names of companies, persons, technologies, publications, countries, and other subjects that are important or of particular interest in that group of documents (although some folder descriptions in the early years are quite spare). They also often reveal background information about or relationships between people, companies, governments, and other institutions.
